Billie Joe Armstrong, the lead singer of Green Day, shared a video celebrating his Johannesburg concert where he changed some lyrics to mock Elon Musk

The rock band blasted the tech billionaire with a spicy lyric swap during its performance at the Calabash South Africa festival in Johannesburg.

Green Day have taken lyrical aim at Elon Musk while performing in his home country of South Africa. The band’s frontman Billie Joe Armstrong reportedly switched a line in their 2004 hit “American Idiot” from “I’m not a part of the redneck agenda” to “I’m not a part of the Elon agenda.”
